iTo all whom, it may concern.-

; Beit known that we,ADRIAN HALL and J OHN M. HALL, of Greenfield, county of Hancock, and State of Indiana, have invented a certain new and useful Conveying Apparatus; and we irlo hereby declare that the following is a full,

. clear, and exact description thereof, reference being had to the accompanying drawings, in ,which like numerals refer to like parts.

The object of this invention is to operate successfully and practically a cable apparatus for conveying material from one point to aniother. It is especially adapted for loading and unloading steamboats at landings and for jexcavating ditches, trenches, sewers, and the ;moving the carrier as desired.

Another feature of the invention consists combining with thedriving means a drum for tightening the supporting-cable and in onnection therewith means for holding the same in a taut condition.

The full nature of the invention will be un- ,derstood from the accompanying drawings and the following description and claims. i In the drawings, Figure l is a perspective gview of the device in operative connection Ewith cables and supports to illustrate its use. ,Fig. 2is a plan view of the operating device with the upper portion of one wheel cut away and parts arranged to move the carrier in one direction. Fig. 3 is the same as the right- ,hand half of Fig. 2 with parts arranged to move the carrier in an opposite direction. gFigAL is the same as Fig. 3 with the lower-drumjdriving wheel idle. Fig. 5 is a vertical secition through the eccentric-bearing and part Fig. 6 is a plan view of the left-hand half of the device with parts arranged to tighten the cable. Fig. 7 is a side elevation of the ratchet with the rim of the gear removed. Fig. 8 is adetail of the brake, and Fig. 9 is a detail of the ball-bearing on the shaft.

In detail,the operating mechanism is mount- }ed upon a frame having a rectangular base 10,

rear uprights 11, and inclined side pieces 12. In the upper part of the frame a drum 13 is mounted, on which a supporting-cable 1a is wound. This cable passes over a pair of forks 15 and is secured at the other end to a dead man 16. The purpose of this upper drum 13 is to tighten said cable 14, for said cable carries a pulley 17, that supports the carrier 18, by which the material, such as bales of cotton or gravel or soil, may be conveyed. The carrier of course is to be modified to suit the material that is to be transported. The upperdrum shaft 19 has secured upon it a gearwheel 20, whereby said drum is actuated. Said gear 20 has on its inner side the ratchet teeth 21, that are engaged by a pawl 22 on a lever 23, extending out in front of the machine, whereby said pawl may be moved into or out of engagement with said ratchet for holding said gear and the upper drum stationary when the supporting-cable 14: has been made taut. Said upper drum and gear are rotated by a pinion 2 on the shaft 25, that carries the sprocket-wheel 26, which is driven from any suitable source of power by a sprocket-chain 27 continuously in one direc-' tion. Said pinion 24 is mounted loosely on the shaft and is put in connection with said shaft by a sliding clutch 28, which is operated by an arm 29, that is slidable in the guides 30, secured on the inclined side piece 12 at the left-hand side of the frame. Said arm is moved by the lever 31 and the connecting-bar 32, arranged as shown.

The lower drum 33 is mounted on the shaft 34, to which the lower-drum-driving gear 35 is secured. This driving-gear has a hub'36, toothed like a gear-wheel, and also an internally-toothed rim 37 on the side next to the frame. An endless cable 38 is coiled about the lowerdrum 33 and is connected with the carrier 18 and runs over a pulley at the remote end of the supportingcable. The carrier is moved along on the supporting-cable by the endless cable 38, operating alternately in one direction or the other, as may be desired.

The actuation of the lower drum in the one direction or the other is effected by a pinion 40, mounted on the right-hand end of the shaft 25 and movable into engagement with the toothed hub 36 of the driving-gear 35 or into engagement with the internallytoothed rim 37 of said gear or into an inter mediate position out of touch with either said hub or rim, so that the gear 35 would run idly, while the carrier might move by IIO gravity along the supporting-cable 14. In order that the pinion 40 may be moved into or out of engagement with the hub or the rim of said driving-gear 35, the shaft 25 is mounted in the eccentric 41, and said eccentric is scillated by an arm 42, a connecting-rod. 43, and a hand-lever 44. The other 'end of the shaft .25 must also be mounted in a slightlymovable bearing, and this is accomplished by mounting it loosely in the ball 45 and mount- A ing the ball loosely in the bearing-cup 46,

secured inthe inclined side piece 12 at the left of the frame. The change of position of the lever 34 is not very great-at least not sufficiently great to interfere with the operation of the gear-wheels.

' This makes a convenient and simple apparatus for moving the load-carrier and for tightening the supporting-cable. When used in connection with a steamboat, the'frame is mounted on thedeck ofthe boat, and the cable is run out and secured upon the landing.

- After the supporting-cable is made taut'by the machine the gear 20 is thrown out of operation by the lever 33 and then the machine runs continuously, moving the carrier in one direction or the other at the will of the operator in charge of the hand-lever 44. If the' carrier needs to be stationary while loading or unloading, he throws the pinion 40 into its tion of a carrier, an endless cable for moving said carrier, a drum for operating said cable, a gear-wheel that actuates said drum, said gear-wheel being provided with an internal and an external series of gear-teeth, a pinion for engaging said gear-teeth, and means for moving said pinion into, and out of operation with either series of gear-teeth.

2. In a conveying apparatus, the combination of a carrier, an endless cable for moving.

said carrier, a drum for operating said cable, a gear-wheel that actuates said drum, said gear-wheel. being providedwith an internal and an external series of gear-teeth, a pinion for engaging said gear-teeth, a frame, a-continuonsly-operating driving-shaft on which said pinion is secured, an eccentric bearing oscillatory in said frame and in which the end of said shaf tad jacent said pinion is mounted, and means for oscillating said eccentric bear- -means for clutching said pinion into opera-i ing so as to move said pinion into or out o: engagement with either series of teeth on saic gear-wheel.

3. In a conveying apparatus, the combina tion of a carrier, an endless cable for moving said carrier, a drum for operating said cable a gear-wheel that actuates said drum, S2.i( gear-wheel being provided with an interna and an external series of gear-teeth, a piniol for engaging said gear-teeth, a frame, a con tinuously-operating driving-shaft on whicl said pinion is secured, an eccentric bearing'os cillatory in said frame and in which the one of said shaft adjacent said pinion is mounted means for oscillating said eccentric bearing so as to move said pinion into or out of en.

gagement with either series of teeth on sait gear-wheel, and a ball-bearing in said 'frami ing. i 4. In a conveying apparatus, a stationary supporting cable. a frame at one end of saic cable, means mounted on said frame for tight ening and holding said cable taut, a carriei movable on said stationary cable, an endless cable for moving said carrier, and means mounted in connection with said frame fol moving said endless cable in opposite directions.

5. In a conveying apparatus, the combinationof a carrier, an endless cable for moving said carrier. a drum for operating said cable, a gear-wheel that actuates said drum,said gear wheel being provided with an internal and a external series of gear-teeth, a pinion for en gaging said gear-teeth, a frame, a continu ously-operating' driving-shaft on which sai pinion is secured, an eccentric bearing oscil latory in said frame and in which the end 0 said shaft adjacent said pinion is mounted means for oscillating said eccentric bearing so as to move said pinion into or out of engagement with either series of teeth on said gear-Wheel, a su pporting-cable on which said carrier moves, a drum mounted in said frame to which one end of said cable is secured for tightening and holding the same, a gear for actuating said tightening-drum, a pinion loosely mounted on said shaft for operating said gearl tive engagement with said shaft, a ratchet sef cured to the gear that actuates said tighten ing-drum, and a lever-controlled pawl for engaging said ratchet.

In witness whereof we have hereunto affixed our signatures in the presence of the witnesses herein named.
